Before his passing, Guru Nanak Dev ji declared that there would be no more Gurus, and Sikhs would follow the teachings in the Sikh holy book, called Guru Granth Sahib, where "Guru" means "teacher" in Sanskrit and Punjabi.[3] Guru Nanak had a close connection with Baba Farid, another Sufi saint, known to the Sikhs as Sant Fariduddin.[4]
When Guru Nanak was a child he refused the upanayana (holy thread) to initiate him into the Hindu religion. Later in his life he married Mata Sulakhani with whom he had two sons. They were called Sri Chand and Lakshmi Das. According to the Sikh religion, one day he was bathing in the river and god took him up to heaven. His family members were very worried as they had thought he died. After three days he returned with the message of god. He gave up his job to spread the message on how to be a good person. Guru Nanak died in Kartarpur.
